Grachev (Moon)

Named after Andrej Dmitrievich Grachev - Soviet rocketry scientist (1900-1964).

Grachev is a lunar impact crater on the far side. It lies to the northwest of the Mare Orientale impact basin, in the outer skirt of ejecta surrounding the Montes Cordillera mountain ring. Passing along the southwestern edge is the Catena Michelson, a valley-like formation composed of a linear chain of small craters. This feature is radial to the Mare Orientale basin.

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
